HJT 3.0. Combining gettering process and double-sided uc-Si to maximize cell efficiency and module power. -0.26%/C Pmax temperature coefficient. More stable power generation performance and even better in hot climate. Small Chamfer Design. Bigger power generation area on the solar cell, increasing 1% cell power of single piece. SMBB design with Half-Cut Technology. Shorter current transmission distance, less resistive loss and higher cell efficiency. Up to 90% Bifaciality. Natural symmetrical bifacial structure bringing more energy yield from the backside. Sealing with PIB based sealant. Stronger water resistance, greater air impermeability to extent module lifespan. Higher reliability. Industrial leading product and performance warranty, ensuring modules consistent outstanding performance. Ideal choice for solar rooftop system. Suitable for various rooftop projects.
